"Breathe" is a song recorded and written by American singer-songwriter Taylor Swift featuring American singer-songwriter Colbie Caillat, taken from Swift's second studio album, Fearless (2008). Produced by Swift and Nathan Chapman, the song is driven by an acoustic guitar and mandolin and features pianos and violins in the production. Lyrically, "Breathe" addresses heartbreak and the loss of a close friendship, though some critics interpreted it as a breakup song. Released on October 21, 2008, as a Rhapsody-exclusive, the song received favorable responses from contemporary music critics. "Breathe" was nominated for the Grammy Award for Best Pop Collaboration with Vocals in 2010. It peaked at number 87 on the US Billboard Hot 100 and was certified gold by the Recording Industry Association of America (RIAA). Swift performed the song live for the first time ever in Miami Gardens, Florida for the Reputation Stadium Tour. Swift and Caillat released a re-recorded version, "Breathe (Taylor's Version)", as part of her 2021 re-recorded album Fearless (Taylor's Version). The re-recorded version charted on the Canadian Hot 100 and the Billboard Global 200. Background and release Swift was very fond of Caillat's 2007 debut album, Coco.

It's the hardest thing to go through. It's crazy listening to the song because you would think it's about a relationship and it's really about losing a friend and having a fallout."
